Welcome to the land of Hudson's Secret Castle where people use music to communicate with each other. From the north, an Evil Warlord and his demons attack the people of Hudson and robs them of their musical instruments. Hudson's Queen Eliza is captured deep inside the Secret Castle.

You must save Queen Eliza and get the musical instruments back. This will not be an easy task. The Secret Castle has many different rooms and each room is a maze filled with demons, secret passages and doors. However, Queen Eliza has hidden many helpful tools, instruments, and money in every room to help you. Use bubbles to help you find the places where they are hidden.

Be very alert and think very quickly to solve the puzzle of each room. Just when you think you've made it, you must face and destroy each of 7 demon-monsters from the Evil Warlord. You are Hudson's last hope!!! GOOD LUCK!!!
